Detailed Description

Abstract base class for the Visitor design pattern.

See Gamma et al 'Design Patterns' Ch. 5 for a description of the Visitor design pattern.

The const in the name refers to the fact that the visitor does not modify the node it visits (or modifies only mutable fields). There is currently no provision for the visitor object itself to be be considered const during a visit.
